SEOUL: North Korea fired an unidentified projectile into its eastern waters, South Korea's Joint Chiefs of Staff (JCS) said Saturday.

Xinhua quoted the JCS as saying in a statement without mentioning further details.

It came just three days after South Korea said North Korea launched a ballistic missile into the eastern waters from the Sunan area in Pyongyang.

North Korea has launched projectiles 15 times this year, saying that it test-fired a new type of intercontinental ballistic missile (ICBM), Hwasongpho-17, on March 24.
